Osprey, a pack company well known among hikers, is entering the bicycle equipment fray this fall with their new Raptor pack.  Using a compression mechanism to create pressure on the reservoir, which pushes the water our of the tube in a consistent flow.  It has bike-tool specific pockets and a helmet clip that holds your helmet in place for when you’re, uh, riding without a helmet.
It’s not shown on their website yet (nothing for cycling is), and this pic was borrowed from BikeBiz who has the full scoop.
